Abstract

The embodiment of the present invention discloses a method and device for color display of a UV oscilloscope. The method includes the following steps: acquiring the YUV value of any pixel of the image; calculating the value of any pixel according to the YUV value of any pixel The ΔYUV value of the pixel displayed on the oscilloscope; the coordinate of any pixel in the oscilloscope is calculated according to the YUV value of any pixel; and the ΔYUV value is displayed on the coordinate. In the embodiment of the present invention, the color oscilloscope is realized by associating the YUV value of the pixel point of the image with the coordinate of the pixel point in the oscilloscope, calculating the coordinate of the pixel point in the oscilloscope and displaying ΔYUV.

Description

technical field [0001] The invention relates to the technical field of video and image processing, in particular to a method and system for color display of a UV oscilloscope. Background technique [0002] RGB (red, green, blue) color space is a common color space in computers, which generates other colors by adding the three primary colors of red, green, and blue. Among them, RGB24 uses 24 bits to represent the color of a pixel, and red, green, and blue each occupy 8 bits, and 256*256*256 colors can be obtained. [0003] The YUV color space is a color-coding method used by the European television system. Among them, "Y" represents the brightness (Luminance or Luma), that is, the grayscale value; while "U" and "V" represent the chroma (Chrominance or Chroma). Color TV adopts YUV space precisely to solve the compatibility problem between color TV and black and white TV with luminance signal Y, so that black and white TV can also receive color TV signal. The YUV we often pr...
